IMPROVEMENT-1N SIGNS ron STREET-LAMPS.

The Schedule referred to in these Letters Patent, -and making part of the same.

To lwhom it may cmwen Be it known that we, ERAsTUs CASWELL and HER- MAN t LACHMANN, of the .city of Chicago, and State of Illinois, have invented certain new and useful Improvementsin Marking and Designating the Names of Streets-on Street-Lamps; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the Lettersv and Yfigures 4marked thereon.

p "The nature and object of our invention is to make the 'names' of streets on street-lamps separate and apart from the glass, so that when the glass is broken yor repeatedly cleaned, the name will not be injured.

Figure 1 represents the glass and frame of an ordinary street-lamp. 4

a is a cross-bar, made 0f tin, or any other suitable material, 'and' at one end is fastened to the frame of' the lamp on the inside bya hinge. The other end is fastened to the other side of the frame by a latch, `or anysnitable means.

I0 this cross-bar is fastened, by soldering or otherwise,the lettering, made from any/suitable material, indicating the name of the street. The lettering and the cross-bar are not in anyway attached to the glass, but lit closely against the glass, so as to be distinctly seen in passing by.

Whenever it is desired to clean the glass, the door of the lamp is opened, the end, fastened-by a latch, is

.swung around on the hinge of the other end, the same as a door is swung around. It is thus removed from the glass desired to be cleaned.

frdm the lamp. Y v

This method of marking and designating the names ot streets on street-lamps, removes the necessity of painting the names on the glass, as it is now practised, and yhas to be renewed every time a glass is broken.

All the lights of the lamp could be broken andthe lettering would not be injured. f

We Vdisclaim the idea of broadly claiming the markin'g or designatingthe names of streets on street-lamps independent of the glass. This has been done before, but suspending or vhinging the lettering from a hinged bar, in the manner shown above, is believed to be new.

Havingtthus described our invention, What we claim as.new, and desire to secure by Letters Patent, is

suspending oi-hanging the letters designating the names of streets on street-lamps by the hinged bar a, for the purpose and in the manner substantially as described.
